ROPE-PULLEY MADE IN TWO PARTS.

Specification of Letters Patent.

Application filed December 7, 1908. Serial No. 466,418.

such as used with the spars of fishing boats and for similar purposes. The improved locking-device is constructed in such a manner that the two parts of the rope-pulley can be easily'unlocked and opened even if the sheave be heavily loaded.

In. the accompanying drawing the improved two-parts rope-pulley is shown by way of example in an elevation, the lockingdev1ee being represented in section.

The rope-pulley consists of the eye-bolt a to the lower transverse part b of which the shanks (Z, c of the sheave-bearing are pivoted by means of bolts 0. The sheave f is made in two parts which are mounted, the one upon the support 5/ of the hook-shaped lock ing-bolt 7L and the other upon the staple 2' having a hollow 7:: adapted to receive the hook of the locking-bolt. The supports 9 and 2' which are made of wrought-steel, are fixed upon the inner surfaces of the shanks (Z, c by means of screw-nuts m and n so that the one stands opposite the other. The support 9 as well as shank cl have a suitable boring for the reception of the locking-bolt h which is revolubly mounted in its support and carries at its outer end a handlever 0. The inner ends of the supports 9, 2' are cone shaped, the one 9 forming the female and the other i the male part.

To lock the rope-pulley which is represented in the drawing in opened position,

hand-lever 0 is turned so that it stands perpendicular to the shank (5 whereby the hookshaped end of locking-bolt h is turned so that it can engage with the staple-opening 70 when the two shanks d, e are pressed the one toward the other. If now the hand-lever 0 be returned to its original position the hookshaped end of the lockingbolt 72. gets behind the shoulder formed in the opening is and the device is locked, so that the two half-sheaves f form a proper sheave adapted to freely turn upon the supports 9, i.

As for certain uses the sheave need not be revoluble the two half-sheaves could be dispensed with, in which case the two supports g, 2 are of such a shape that their outer surfaces form the rope-groove.

I claim An improved rope-pulley made in two parts, comprising in combination with the eye-bolt having a transverse lower end, two shanks pivoted to said transverse part and having each a boring near its free end, a support fixed in the boring of one of the shanks having a central boring and forming the female part of a conecoupling, a hookshaped locking-bolt revolubly mounted in. the central boring of said support, a handlever fixed upon. the outer end of said locking-bolt, a support fixed in the boring of the other shank having a staple opening for the reception of the hooleshaped end of the locking-bolt and forming the male part of a conecoupling and two half-sheaves revolubly mounted upon said supports so as to form a sheave when the shanks be locked, sul'istantially as described. and for the purpose set forth. 1

In witness whereof I have hereunto set my hand in the presence of two witnesses.
